Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The disclosure relates generally to boot systems and methods, more particularly to boot systems and methods using an input/output chip of an electronic device, and related devices.

2. Description of the Related Art

Generally, an OS (Operating System) must be in a data storage device, such as hard disc of a computer system. The OS includes hardware drivers and applications used to boot the computer system, and provides functions when the computer system operates.

A recovery disc is always provided with a computer system. When the computer system has a malfunction, for example, the hard disk or OS of the computer is damaged, or files in the hard disk are infected with computer viruses, such that the computer system cannot boot or results in abnormal operation, the recovery disc can be used to boot the computer system, and recover the OS of the computer system. However, if the recovery disc is lost or a disc drive of the computer system cannot be driven to read data of the recovery disc, the computer system cannot be successfully recovered.

Additionally, in some conventional practices, a computer system may have a hard disk including multiple partitions or several hard disks. Various Oss can be stored in the respective partitions/hard disks. When an OS of a specific partition/hard disk malfunctions, another partition/hard disk can be switched to, and the computer system can be booted according to the OS therein. However, in these conventional practices, additional hard disk capacity is required to store the backup OS, thus increasing the cost of the computer system.

DETAILED DESCRIPTION OF THE INVENTION

Boot systems and methods, and related boot devices are provided.

FIG. 1 is a schematic diagram illustrating an embodiment of a boot system of the invention.

The boot system 1000 can be used in an electronic device, such as a computer system. The boot system 1000 comprises a BIOS (Basic Input/Output System) 1100, a hard disk 1200, an IO (Input/Output) chip 1300, and a memory device 1400. The BIOS 1100 is a firmware stored in a ROM (Read Only Memory) on the motherboard of the computer system. The BIOS 1100 can control basic input/output of the computer system, configure the computer system, and perform hardware tests and other functions. The hard disk 1200 can comprise an original OS (Operating System), and corresponding system files and applications (not shown in FIG. 1). The hard disk 1200 may be the master boot device of the electronic device. That is, in general situations, the BIOS 1100 can control the electronic device to boot from the hard disk 1200, and boots the electronic device according to the original OS in the hard disk 1200. The IO chip 1300 and the memory device 1400 can be integrated as a boot device. FIG. 2 is a schematic diagram illustrating an embodiment of a boot device of the invention. As shown in FIG. 2, the boot device 2000 comprises the IO chip 1300 and the memory device 1400. The IO chip 1300 may be a super IO or a keyboard controller. The memory device 1400 may be a flash memory coupled to the IO chip 1300 via an interface 1500, such as a SPI (Serial Peripheral Interface) NVM (Non-Volatile Memory) interface. It is understood that, the memory device 1400 is not limited to any type of flash memory, and the interface between the IO chip 1300 and the memory device 1400 may be variety based on the type of flash memory. The above interface is an example of the application, and the invention is not limited thereto. The memory device 1400 can comprise a rescue OS 1410, a repair utility 1420, and/or drivers (not shown) for the hardware of the electronic device. The rescue OS 1410 and the repair utility 1420 can be used to boot the electronic device. Related details will be discussed further in the following paragraphs.

FIG. 3 is a flowchart of an embodiment of a boot method of the invention. The boot method can be used in an electronic device, such as a computer system.

In step S302, the rescue OS 1410 is read from the memory device 1400 via the chip 1300. Then, in step S304, the rescue OS 1410 is executed to boot the electronic device.

It is noted that, as described, in general situations, the BIOS 1100 controls the booting of the electronic device by the hard disk 1200. Therefore, when the hard disk 1200 cannot be detected by the BIOS 1100, the embodiment in FIG. 3 is performed. Additionally, in some embodiments, the boot system 1000 can further comprise a temperature sensor to detect the temperature of the hard disk 1200. When the temperature of the hard disk 1200 exceeds a predefined value, the embodiment in FIG. 3 is performed. Further, in some embodiments, the BIOS 1100 can provide a multi-boot menu. Users can select a location, such as the hard disk 1200 or the memory device 1400 to boot the electronic device via the multi-boot menu. When the memory device 1400 is selected, the embodiment in FIG. 3 is performed.

FIG. 4 is a flowchart of another embodiment of a boot method of the invention. The boot method can be used in an electronic device, such as a computer system.

In step S402, the rescue OS 1410 is read from the memory device 1400 via the chip 1300. In step S404, the rescue OS 1410 is executed to boot the electronic device. Then, in step S406, the repair utility 1420 is read and executed from the memory device 1400 via the IO chip 1300, thus to check and/or repair the hard disk 1200. It is understood that, in some embodiments, the repair utility 1420 can check at least one system file in the hard disk 1200, and repair the system file. It is noted that, in some cases, the drivers for the hardware of the electronic device in the memory device 1400 can be also read and reinstalled. In some embodiments, when the repair utility 1420 is executed, the repair utility 1420 can connect to a server via a network according to a predefined URL (Uniform Resource Locator). The server can be set up and maintained by a manufacturer of the electronic device. The server can perform on-line virus scan and/or system repair for the electronic device via the network.

When the check and/or repair is completed, in step S408, the check result of the hard disk 1200 is stored, displayed via a display unit (not shown) of the electronic device, and/or transmitted to the server corresponding to the manufacture of the electronic device via the network. It is understood that, the check result may be related to details of actions performed by the repair utility 1420, the check and repair result of the system file, and/or notices for users when the repair of the hard disk 1200 cannot be completed. Users can view the related information of the repair when they see the check result. When the manufacture receives the check result from users via the server, the check result can be recorded, and/or related utilities or materials required for repair can be prepared in advance, thereby speeding up the repair procedure. In some embodiments, when the system repair for the hard disk 1200 is completed, the BIOS 1100 can reboot the electronic device according to the original OS in the hard disk 1200.

It is understood that, similarly, in some embodiments, when the hard disk 1200 cannot be detected by the BIOS 1100, the embodiment in FIG. 4 is performed. Additionally, in some embodiments, the boot system 1000 can further comprise a temperature sensor to detect the temperature of the hard disk 1200. When the temperature of the hard disk 1200 exceeds a predefined value, the embodiment in FIG. 4 is performed. Further, in some embodiments, the BIOS 1100 can provide a multi-boot menu. Users can select a location, such as the hard disk 1200 or the memory device 1400 to boot the electronic device via the multi-boot menu. When the memory device 1400 is selected, the embodiment in FIG. 4 is performed.

Therefore, the boot systems and methods can directly boot an electronic device using a memory device coupled to an IO chip of the electronic device. Since the IO chip is a necessary component of the electronic device, such as the computer system, the cost for preparing a recovery disc or adding capacity to a hard disk required for system recovery in conventional practices can be reduced. Additionally, the response and repair time can be shortened when users face computer malfunctions, thus increasing satisfaction of users.

Boot systems and methods, or certain aspects or portions thereof, may take the form of a program code (i.e., executable instructions) embodied in tangible media, such as floppy diskettes, CD-ROMS, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine thereby becomes an apparatus for practicing the methods. The methods may also be embodied in the form of a program code transmitted over some transmission medium, such as electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the disclosed methods. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates analogously to a specific logic circuit.

While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. Those who are skilled in this technology can still make various alterations and modifications without departing from the scope and spirit of this invention. Therefore, the scope of the present invention shall be defined and protected by the following claims and their equivalents.
